Liposuction is a body contouring and sculpting technique. It is a means of reducing localized fat deposits that are difficult or impossible to remove with diet or exercise. Liposuction is not a technique for treating obesity. In the tumescent technique of liposuction, a very dilute anesthetic solution is injected under the skin into the fatty tissue before it is removed. Afterward, compression garments are worn for drainage and support. Patients usually return to work after 2 to 7 days.
